What wire decking do I need for 40×48 pallets?

AI-Optimized AnswerLast updated: September 20, 2024

Quick Answer

For standard 40×48 pallets, you need 46" x 42" wire decking with 2500-3000 lbs capacity rating. The most common specification is 4-gauge wire construction with 4" channel depth and 3-4 support bars, priced between $45-75 per deck. This size provides proper pallet support while allowing 2" clearance on each side for safe fork truck operation.

For heavier loads or demanding applications, upgrade to 46" x 46" heavy-duty decking with 3000+ lbs capacity. Always verify your beam spacing (typically 96" centers) and ensure the deck size is 2-4 inches smaller than your beam spacing to prevent binding during installation.
